Application tiled July 13,1906. Serial. No.' 326,150,

To all whom it may concern:

Be it known that I, WILLIAM BIEBER, a citizen of the German Em ire, residing'at New York, in the county o New York and State of NewYork, have invented certain new and useful Improvements in Means for' Making Fire roof Walls, o f which the following is a speci cation.

The invention to relates to means for `making fireproof walls in or forming part of a building, and Vmore particularly to such walls as are formed of a quick-setting composition. In the forma tion of such walls it is desirable that the apparatus employed may have a wide range of application not only in the formation of walls during the construction of a building,- but also in construction of such walls in buildings already erected. ,P Such walls require to be of different..thicknesses andof varying heights, the/walls being also preferably formed as a Ysubstantially one-piece or'continuous structure.

With these general considerations in view the object of the present invention is to provide a device of the character referred to which shall be simple in construction, easy of manipulation, readily put up or taken down, and wherein the parts maybe adjusted for the formation of fireproof walls of widely-diff ferent forms and sizes.

The invention-consists of the parts f and combinations to be hereinafter fully de# scribed and then denitely pointed out in the claims. f

vIn the drawings which illustrate one of the practical embodiments of the present invention,'Figure 1 is a general side view of the den vice in use. Fig. 2 is a sectional v iew on the line Fig. 1. Fig. Sis an enlarged de-A tached view-of one en d of a wallfformation board, -showing the bearing strip and rollers.

gagement of thebearing-strip therewith; and Fig'. 5 is a like view showing the bearing-rolle engagement with the post-track.

' f r` In the formation of iireproofwalls, eitherin' the erection of .buildings or in providing artitions in buildings already erected, one o the important considerations is to employ a composition which will set quickly and when set will' be self-sustained, free from. cracks, and

be hereinafter described.-

substantially continuous, and I employ in the' present instance such compositions in which cement or asbestine, sand, caustic potash, and water constitutethe principal constituents.

In the drawings, A represents the exterior walls of a buildin A the floor, and A2 the ceiling lor roof, al of which may be of any usual or desired construction. The drawings illustrate the formation of a. comparatively short section. of interior-ireproof wall but it is to be understood that itmay be more extensive and may be the exterior wall itself.

Disposed between theiioor A and ceiling or roof A2 are the series of `posts B B, which v -are preferably formed of T metal, as shown,

although other suitable material may obviously be-employed, the said osts being disposed in pairs, as shown by BP ig. 2, the posts of each pair being a distance apart equal" to the thickness of the wall to be formed. These posts are secured in place by means of wedges vb b, reversely inclined, as shown in Fig. 1,-

and when driven in place between'the ceiling or roof A2 and the top of the post they may be locked by means of a pin b2, which engages locking-notches in the adjacent surfaces of the wedges. It will be noted that the locking-notches in the wedges b are disposed at diiierent relative positions along the wedge' incline, so that as the wedges are driven more or less to place at least a pair of notches will coincide at some point along the wedge incline and enable the locking-pin to engage them.

dimensions to extend between adjacent posts, as shown, and at each end theyy are pro,- vided with bearing-strips c, which .overlap the side iianges of the posts B and position the formation-boards C, so that the 'inner-'surfacesv thereof extend in the same plane with the inner surfaces of osts B, with the'result lthat upon removal o the posts and boards the material forming thezwall willM resent a uniform' and continuous surface. he bear# ing-strips c maybe secured in their overlapping position. to the wformation-boards C by' any suitable means-as`, for instance, the

boltsc. d

formation-boards C ing-bolts d dat each end, which engage appropriatefloles or perforations iny the'out.-

The wall-formation boards C are of properV wise thereof near the wardly-extended flange of the T-posts B, as best indicated in Fig. 2 and as will be readily understood by oneskilled in the art.

. AFrom the construction thus far described it will be noted that the 'posts B B being fixed in position the formation-"boards C C are secured in pairs, oneopposite the other, to the posts by means of the sliding bolts'd d, the bearing-strips e at such times correctly positioning the inner surfaces of the formationboards in the plane of the inner surfacel of the posts. The composition is now placed between theopposed boards, and when it sets theboards are loosened by withdrawingthe bolts d d and raised so that their Alower edges just overlap the set composition below, whereupon the operation is repeated. During the raising of the formation-boards the bearing-strips travel along the flangeof the posts, as upon a track. The lbearing-boards,

however, are necessarily made sufficiently -lieavy to withstand the use to which they are put, and braces f f may extend lengthtop and bottom. Between the top and bottom edges of the formation-.boards the bearing-strips c are preferably provided with a cireularly-sha-ped recess h h', Fig. 3, and seated therein are the guide-wheels 71, h, the peripheries whereof eX- tend beyond the outer edge of the' bearing strips c and contact with the side of the central flange of the T-post-s B, which acts as a track for the upward movement of the formation-boards. i

In Figs. 4 and 5 a slightly-modified form `of the posts are shown wherein the posts B the extentv of the wall yet detachably put in this last layer of com osition.

' are provided also with a bead b1 on each side of the central web, and between thisbead and the lower flange is thus formed a guide or track way for the bearing-strip and guide,.-l wheels, as indicated, which will thus resist any outward movement of the formationboards. i

From the construction described it will be seen that the posts are readily, securely, and place; that there may be any number of these desired, according to to be made; that the formation-boards may be readily put ii'i piace, beginning at the lower part of the wall to be made, and after the composition M has become set between opposed formationboards that these may be readily raised to make another superposed mass, and so on to the top. AWhen the top is reached, only-one formation-board ofa pair lis put in place,.to thereby leave a space for the introduction of .ployed-to smooth over the exposed side of When the wall thus constriicte has properlv set, which it will do in a few minutes, the formation-.board and posts are removed, the wedges lending themselves readily to displacement -the combination of a series of posts, wedges for this purpose. It is obvious, of course, that the posts might be put permanently in place, if desired Having thus described my invention, what I claim, and desire to secure by Letters Patent, is v l.
